I recently switched from a blackberry 7100i over to the sprint 8830 (girlfriend hated my old phone so she got me to switch). During my 1 1/2 period with the 7100i I had various problems that nextel customer care and bbforums helped me with. I switched over to the 8830 on the 28th of august and it was pretty nice....UNTIL I started having problems with my bill! Sprint has horrible customer service and your best bet is to asked to speak to someone higher then the customer service rep your talking to.
